Thanks for the suggestion on the mailop list Jim.
Verizon began accepting mail again for lists on the European server
about 6 hours ago.
No light was shed as to why or what changed their view. Not only Verizon
but AT&T as well, at around the same time - a little puzzle that's
probably best left alone.
It may be that their default position is to block all list mail
regardless - until they get swamped with complaints.
I've subscribed to the mailop list as you suggest, and if I learn
anything relevant to this issue I'll post it back here.
Thanks,
Mark

All the DNS records (inc SPF, DKIM) are in place, the server is on no RBLs,
con-current connections to the recieving mail servers is set at 2 in
Postfix. In short, all the right boxes are ticked as far as we can see.
Point noted about the time needed to build a good IP reputation. In light of
that, we moved the list to our old established server in Europe. It has a
SenderScore of 99, and of course all the same boxes are ticked. Verizon
still rejected list mail.

A good place to start is on the mailop list, explain your company and
sign-up practices/filtering, etc. Be open and ask for specific reps
to contact you offline if necessary. You may get some awesome help,
although this close to the holidays your message may not hit the right
people until next year.
